overview:

high voltage insulation megohmmeter is composed of medium and large scale integrated circuits. this meter has large output power high short-circuit current value and large output voltage grades (there are four voltage grades). the working principle is as follows: the dc high voltage generated by the battery inside the machine as power supply and converted by dc/dc reaches the l pole from the e pole by the tested product so as to generate a current from e to l pole. after i/v conversion and operation by the divider the measured insulation resistance value is directly displayed by lcd.
